TECHNICAL FIELD

The present invention relates to a wrap case for packaging, and in particular to a wrap case for packaging, which is characterized in that a component for fixing a wrap is integrally provided, not separately, in order to fix the wrap, so the wrap is prevented from moving during the packaging of a predetermined thing, and a packaging work is easy, and the weight is light while effectively protecting the built-in wrap along with an easier recycling. Safety may be enhanced since metallic teeth are not used.

BACKGROUND ART

A predetermined container filled with food is generally sealed using a wrap in order to prevent the food from being oxidized as the food comes into direct contact with air. Such a wrap is a packaging material made from a synthetic resin in a form of film and is configured to maintain the freshness of food in such a way to seal the container containing a variety of foods.

The related packaging wrap is wound on a cylindrical winding roll and is accommodated in a predetermined shaped packaging wrap case. Such a related packaging wrap is manufactured by bending a sheet of paper into a rectangular parallelepiped shape wherein a cover is integrally provided while leaving one side of the rectangular parallelepiped open. In order to cut the wrap, metallic teeth are formed along one edge of the above open side.

In the above-described related wrap case, the winding roll is simply inserted inside of the case, not fixed to the case. When a user unwinds the wound wrap when in use, the wound roll moves inside of the case, so cutting the wrap properly becomes hard.

When the wound roll moves, it may roll out of the case. In order to prevent the wound roll from rolling out of the case, the user needs to hold the wrap tightly. Since the related wrap case is made from paper, if the user holds the wrap tightly, the wrap case may be easily crushed, thus damaging the wrap accommodated inside of the wrap case. When the user packs a predetermined container using a packaging wrap while holding the related wrap case with a hand, the metallic teeth of the wrap case may hurt the user's hand due to the user's carelessness.

As one of the related art, the Korean Patent Publication Number 10-2010-0100460 describes a wrap cutter for packaging.

The front surface plate 11 and the first rear surface plate 13 correspond to each other in their shapes and extend from both long side portions of the first bottom plate 10 and are folded into a shape vertical with respect to the first bottom plate 10.

The first side surface plate 15 extends from both short side portions of the first bottom plate 10, and the first reinforcing plate 16 extends from an outer side edge of the first side surface plate 15. The connection plates 12 and 14 extend from both short side portions of the first front surface plate 11 and the first rear surface plate 13 and are folded into a shape vertical with respect to each of the first front surface plate 15 and the first rear surface plate 13. At this time, the facing connection plates 12 and 14 of the first front surface plate 11 and the first rear surface plate 13 are folded into a shape wherein they are overlapped on each other. In addition, the both sides of the first bottom plate 10 protrude more than the both sides of the first front surface plate 11 and the first rear surface plate 13, so the folded connection plates 12 and 14 are positioned at the first bottom plate 10. In addition, the first side surface plate 15 surrounds the outer sides of the folded connection plates 12 and 14, and the first reinforcing plate 16 surrounds the inner sides of the folded connection plates 12 and 14.

The second front surface plate 17 extends from a longer side of the top of the front surface plate 11 which is folded, and the second bottom plate 18 extends from a longer side of the second front surface plate 17.

The second side surface plate 20 extends from both short side portions of the second bottom plate 18, and the second reinforcing plate 22 extends from an outer side edge of the second side surface plate 20. At this time, in the illustrated exemplary embodiment of the present invention, at the second side surface plate 20, there is formed a shaft hole 21 into which an end of the paper pipe 2 on which the wrap 3 is wound is inserted. Alternatively, such a shaft hole 21 may be formed at the second reinforcing plate 22.

The second front surface plate 17, the second bottom plate 18 and the second rear surface plate 19 are overlapped on the first front surface plate 11, the first bottom plate 10 and the first rear surface plate 13, respectively. The second surface front surface plate 17 and the second rear surface plate 19 are formed into a shape vertical to the second bottom plate 18 along with the first front surface plate 11 and the first rear surface plate 13.

The second side surface plate 20 is folded into a 0shape vertical to the second bottom plate 18, and the second reinforcing plate 22 is folded into a shape that it is overlapped on the second side surface plate 20. At this time, the second reinforcing plate 22 comes into face contact with the first reinforcing plate 16. As illustrated in FIG. 1, the second side surface plate 20 having the shaft hole 21 is positioned inside of the finished wrap case 1.

An auxiliary folding part 23 extends from a longer side of the second rear surface plate 19, and the auxiliary folding part 23 is folded and finished coming into face contact with the first rear surface plate 13.

The upper surface cover plate 24 extends from a longer side of the top of the folded first rear surface plate 13 and is formed of the first front surface plate 11, the first bottom plate 10 and the first rear surface plate 13, thereby covering the opened upper side. At this time, the upper surface cover wing 25 extends from both short side portions of the upper surface cover plate 24.

The front surface cover plate 26 extends from a longer side of the upper surface cover plate 24 and is formed on an outer side of the first front surface plate 11. At this time, the front surface cover wing 27 extends from both short side portions of the front surface cover plate 26, and a finish wing 28 extends from an outer side of the front surface cover wing 27. A finish protrusion 28 a protrudes from an outer side of the finish wing 28. A slit 26 a into which the finish protrusion 28 a of the finish wing 28 is inserted is formed where the front surface cover plate 26 and the front surface cover wing 27 are folded.

The front surface cover wing 25 is inserted into between the front surface cover wing 27 and the finish wing 28, so the front surface cover plate 26 keeps being vertical to the upper surface cover plate 24. Also, the inner side of the finish wing 28 surrounds the outer side of the first side surface plate 15.

The guide part 29 extends from a longer side of the front surface cover plate 26 in such a manner as to overlap an inner side of the front surface cover plate 26. At this time, the cutter 40 is provided at the guide part 29. The cutter 40 comprises a cutter holder 41 slidably engaged along the guide part 29, and a cutter blade 42 secured to the cutter holder 41. The cutter blade 42 is vertical to the front surface cover plate 26.
